Abstract

The invention relates to a continuous moving bed light filter, which is applied to the field of water treatment. The continuous moving bed light filter comprises a filter body (1), a water distribution filter plate (2), an ascending pipe (3), a propeller (4), a descending pipe (5), a pollution discharge part (6), a water outlet part (7), an emptying part (8) and light suspended fillers (9). Sewage enters a filter bed of the suspended filler (9) through the water distribution filter plate (2), suspended matters in the sewage are carried by the suspended filler (9) to rise and are separated in an expansion joint of the ascending pipe (3), and the clean filler (9) passes through the descending pipe (5) under the action of the propeller (4) for reuse. The sewage at the expansion joint is discharged through a sewage discharge part (6). The clean water flows downwards through the filter layer and is discharged through the water outlet component (7). The invention has the characteristics of simple structure, continuous operation, automatic cleaning, energy saving, water saving and high efficiency.

Description

Continuous moving bed light filter
Technical Field
The invention relates to a continuous moving bed light filter, which is used for filtering and purifying sewage containing suspended matters and turbidity and is a treatment process or equipment in the field of municipal water supply and environment-friendly wastewater treatment.
Background
Filtration is an important water treatment technology, and is mainly used for intercepting suspended matters and turbidity in sewage to obtain clear water quality. Conventional filter media are typically a graded combination of cobblestones, gravel, and silica sand. After the filter operates for a certain time, the granular substances block the gaps and the surface of the filter material and need to be back-flushed by water and gas. The water and gas back washing needs back washing of a water pump and a blower, and more energy consumption is consumed. Meanwhile, the filter is required to stop producing water during water-air backwashing, which affects the production capacity. Therefore, the purposes of saving energy, reducing emission and improving efficiency can be realized by developing a flushing-free and continuous operation filtering technology.
The novel filter medium (filter material) is light, hydrophobic, chemically stable and good in elasticity, automatically floats upwards during filtering operation, and carries and discharges suspended matters; the filter material for releasing the sludge is reused by a low-energy propeller. Compared with the traditional filtration, the mechanical weight of the patented equipment is greatly reduced, and the patented equipment can automatically discharge sewage and continuously run.
Description of the invention
The invention aims to solve the problems of shutdown flushing and flushing energy consumption of the traditional filter and provides a novel filter which is simple in structure, automatic in pollution discharge, continuous in operation, energy-saving and efficient.
The technical scheme of the invention is as follows:
the continuous moving bed light filter of the invention mainly comprises: the filter comprises a filter body (1), a water distribution filter plate (2), an ascending pipe (3), a propeller (4), a descending pipe (5), a pollution discharge part (6), a water outlet part (7), an emptying part (8) and a light suspended filler (9).
Sewage enters a filter bed of the suspended filler (9) through the water distribution filter plate (2), suspended matters in the sewage are carried by the suspended filler (9) to rise and are separated in an expansion joint of the ascending pipe (3), and the clean filler (9) passes through the descending pipe (5) under the action of the propeller (4) for reuse. The sewage at the expansion joint is discharged through a sewage discharge part (6). The clean water flows downwards through the filter layer and is discharged through the water outlet component (7).
The light suspension filter material has the characteristics of light weight, hydrophobicity, chemical stability, good elasticity and the like, automatically floats upwards during the filtering operation, and carries and discharges suspended matters; the filter material for releasing the sludge is reused by a low-energy propeller. Compared with the traditional filtration, the mechanical weight of the patented equipment is greatly reduced, and the patented equipment can automatically discharge sewage and continuously run. Meanwhile, auxiliary equipment such as a blower, a back washing water pump and the like is omitted, the loss of a filtering head is low, the land is saved compared with the traditional filtering technology, the energy consumption is reduced, and the operation control is simpler and more convenient, so that the invention has good practicability.

Detailed Description
Referring to fig. 1, the present invention relates to a continuous moving bed light filter comprising: the filter comprises a filter body (1), a water distribution filter plate (2), an ascending pipe (3), a propeller (4), a descending pipe (5), a pollution discharge part (6), a water outlet part (7), an emptying part (8) and a light suspended filler (9).
Sewage enters a filter bed of the suspended filler (9) through the water distribution filter plate (2), the suspended filler (9) carries suspended matters in the sewage to rise, the separation of the filler and the sewage is realized in an expansion joint of the ascending pipe (3), and the clean suspended filler (9) is forced to pass through the descending pipe (5) for repeated use under the action of the propeller (4), so that the updating of a filter layer of the suspended filler is realized. The sewage (sludge) at the expansion joint is discharged through a sewage discharge part (6). The clean water flows downwards through the filter layer and is discharged through the water outlet component (7). When the filter is overhauled, sewage can be emptied through the emptying component (8).
